   ...THERE IS A MDT RISK OF SVR TSTMS FROM NW TX INTO SW OK...
   
   ...THERE IS A SLGT RISK OF SVR TSTMS FROM THE SRN PLAINS NEWD
   THROUGH THE OH VALLEY...
   
   ...SRN PLAINS...
   
   EARLY THIS EVENING...A MYRIAD OF BOUNDARIES EXISTS OVER THE SRN
   PLAINS. THE DRYLINE EXTENDS FROM W TX INTO THE SRN TX PANHANDLE
   WHERE IT INTERSECTS A SWD MOVING BOUNDARY THAT EXTENDS FARTHER EAST
   THROUGH NRN OK. SEVERAL OTHER MORE SUBTLE OUTFLOW BOUNDARIES EXIST
   FROM THE TX PANHANDLE EWD THROUGH OK. STORMS THAT INITIATED ALONG
   THE DRYLINE AND SWRN PORTION OF AN OUTFLOW BOUNDARY OVER NW TX AND
   THE TX PANHANDLE PERSIST AS DISCRETE SUPERCELLS FROM NWRN TX INTO
   SWRN OK. VERY LARGE HAIL WILL BE THE MAIN THREAT WITH THIS
   ACTIVITY...BUT ISOLATED TORNADOES WILL REMAIN POSSIBLE NEXT FEW
   HOURS. OTHER MORE LINEAR STORMS ARE DEVELOPING ALONG THE SWD MOVING
   BOUNDARY ACROSS NRN OK. DAMAGING WIND AND HAIL SHOULD BE THE MAIN
   THREATS WITH THIS LINE. THE WARM SECTOR ACROSS OK AND NWRN TX
   REMAINS MODERATELY UNSTABLE WITH STEEP LAPSE RATES AND MLCAPE FROM
   2000 TO 2500 J/KG. LOW LEVEL SHEAR IS NOT PARTICULARLY STRONG...BUT
   SHEAR THROUGH A DEEPER LAYER WILL REMAIN MORE THAN SUFFICIENT TO
   MAINTAIN ORGANIZED STORMS. LATER THIS EVENING AND TONIGHT...ACTIVITY
   WILL PERSIST ONE OR MORE MCSS AS IT SPREADS SEWD THROUGH OK AND NRN
   TX WITH A CONTINUED THREAT OF MAINLY LARGE HAIL AND DAMAGING WIND.
   
   
   ...OH VALLEY AREA...
   
   
   SEVERAL LINES OF STORMS CONTINUE OVER THE OH VALLEY THIS EVENING.
   ONE LINE EXTENDS ALONG A PRE-FRONTAL SURFACE BOUNDARY FROM SERN
   LOWER MI SWWD THROUGH IND. ANOTHER LINE EXTENDS ACROSS ERN OH. OWING
   TO STABILIZING EFFECTS OF EARLIER STORMS...THE ATMOSPHERE REMAINS
   ONLY MARGINALLY UNSTABLE OVER THE OH VALLEY FROM IL EWD THROUGH OH.
   HOWEVER...STRONG LOW-MID LEVEL WIND FIELDS WITH 50 KT BETWEEN 1 AND
   2 KM PERSIST IN THIS REGION DOWNSTREAM FROM EWD ADVANCING UPPER
   TROUGH. THIS WILL MAINTAIN THREAT OF PRIMARILY DAMAGING WIND NEXT
   FEW HOURS AS ACTIVITY CONTINUES EAST AS ORGANIZED LINES. STORMS
   CURRENTLY MOVING EWD THROUGH OH ARE EXPECTED TO BECOME ELEVATED AND
   WEAKEN LATER THIS EVENING AS THEY MOVE TOWARD THE MORE STABLE REGIME
   IN PA. STORMS OVER SRN IL THROUGH IND MAY BE MORE PERSISTENT.
